In this study, a series of tribological tests were conducted on pin-on-disc tester to study the lubrication mechanism SiO2 nanoparticles under different surface roughness considering various loads and velocities. For comprehensive understanding nanoparticles, base fluid was also employed as contrast. Results show that reductions friction coefficients wear scar widths increase with decrease roughness, due in rolling effect self-repairing nanoparticles. The is when height-diameter ratio (λ)...
